Virtual Relation + Assembler doesn't work

[Mathieu Geissler]

Describe the bug
I have a virtual relation in my DTO

@ObjectType('Test')
@Relation('user', () => UserDto, {
  dtoName: 'UserDetails',
  relationName: 'user',
  nullable: true,
})
@QueryOptions({ defaultResultSize: 100 })
export class TestDto {
  @IDField(() => ID)
  id: string;
  @FilterableField({ nullable: true })
  status: number;
  @FilterableField(() => GraphQLJSONObject, { nullable: true })
  Details: TestDetailsDto;
}

@QueryService(TestEntity)
export class TestEntityRelationQueryService extends RelationQueryService<TestEntity> {
  constructor(
    @InjectQueryService(TestEntity)
    queryService: QueryService<TestEntity>,
    @InjectQueryService(UserEntity)
    usrQueryService: QueryService<UserEntity>,
  ) {
    super(queryService, {
      user: {
        service: usrQueryService,
        query(t) {
          return { filter: { id: { eq: t.Details.UserId } } };
        },
      },
    });
  }
}

It's working fine without assembler.
But when I add assembler :

@Module({
  imports: [
    TypeOrmModule.forFeature([TestEntity, UserEntity]),
    NestjsQueryGraphQLModule.forFeature({
      imports: [
        NestjsQueryTypeOrmModule.forFeature([
          TestEntity,
          UserEntity,
        ]),
      ],
      assemblers: [TestAssembler],
      services: [
        TestEntityRelationQueryService,
      ],
      resolvers: [
        {
          DTOClass: TestDto,
          ServiceClass: TestEntityRelationQueryService,
          AssemblerClass: TestAssembler,
        },
        {
          DTOClass: UserDto,
          EntityClass: UserDto
        },
      ],
    }),
  ],
})
export class EntitiesModule {}

The virtual relation is not found (TestEntityRelationQueryService is not used at all)

Have you read the Contributing Guidelines?

Yes

To Reproduce
Steps to reproduce the behavior:

1. Create two entity with dto
2. Add virtual relation in first dto to second dto
3. Add assembler for first dto

Expected behavior
It should use custom RelationQueryService when Assembler is define
